 ### Steps
 1. Create an SNS Topic:
 
 ```bash
-aws sns create-topic --name {studentName}OrderCreatedTopic
+aws sns create-topic --name tvaltnOrderCreatedTopic
 ```
 If successful, you will see in your terminal a JSON response that includes `"TopicArn": "...`.

-aws sqs create-queue --queue-name {studentName}OrderQueue
+aws sqs create-queue --queue-name tvaltnOrderQueue
 ```

 ```
 
 You don't need to save the generated SubscriptionArn.
 
 3. Create an EventBridge Event Bus:
 
 ```bash
-aws events create-event-bus --name {StudentName}CustomEventBus --region {region}
+aws events create-event-bus --name tvaltnCustomEventBus --region eu-north-1
 ```
 
 4. Create an EventBridge Rule:
 
 ```bash
-aws events put-rule --name {StudentName}OrderProcessedRule --event-pattern '{\"source\": [\"order.service\"]}' --event-bus-name {StudentName}CustomEventBus
+aws events put-rule --name tvaltnOrderProcessedRule --event-pattern '{\"source\": [\"order.service\"]}' --event-bus-name tvaltnCustomEventBus

 5. Subscribe the SQS Queue to the SNS Topic
 
 ```bash
-aws sqs get-queue-attributes --queue-url https://sqs.{region}.amazonaws.com/637423341661/{studentName}OrderQueue --attribute-name QueueArn --region {region}
+aws sqs get-queue-attributes --queue-url https://sqs.eu-north-1.amazonaws.com/637423341661/tvaltnOrderQueue --attribute-name QueueArn --region eu-north-1

-aws sns subscribe --topic-arn arn:aws:sns:{region}:637423341661:{studentName}OrderCreatedTopic --protocol sqs --notification-endpoint arn:aws:sqs:{region}:637423341661:{studentName}OrderQueue --region {region}

 ```
 
 6. Grant SNS Permissions to SQS
 
 
 In Bash/Unix terminals you can run this command:
 ```bash
-aws sqs set-queue-attributes --queue-url https://sqs.{region}.amazonaws.com/637423341661/{studentName}OrderQueue --attributes '{"Policy":"{\"Version\":\"2012-10-17\",\"Statement\":[{\"Effect\":\"Allow\",\"Principal\":{\"AWS\":\"*\"},\"Action\":\"SQS:SendMessage\",\"Resource\":\"arn:aws:sqs:{region}:637423341661:{studentName}OrderQueue\",\"Condition\":{\"ArnEquals\":{\"aws:SourceArn\":\"arn:aws:sns:{region}:637423341661:{studentName}OrderCreatedTopic\"}}}]}"}' --region {region}
+aws sqs set-queue-attributes --queue-url https://sqs.eu-north-1.amazonaws.com/637423341661/tvaltnOrderQueue --attributes '{"Policy":"{\"Version\":\"2012-10-17\",\"Statement\":[{\"Effect\":\"Allow\",\"Principal\":{\"AWS\":\"*\"},\"Action\":\"SQS:SendMessage\",\"Resource\":\"arn:aws:sqs:eu-north-1:637423341661:tvaltnOrderQueue\",\"Condition\":{\"ArnEquals\":{\"aws:SourceArn\":\"arn:aws:sns:eu-north-1:637423341661:tvaltnOrderCreatedTopic\"}}}]}"}' --region eu-north-1
+```
+
+With a json file instead (Run this from the root directory of this repo):
+```bash
+aws sqs set-queue-attributes --queue-url https://sqs.eu-north-1.amazonaws.com/637423341661/tvaltnOrderQueue --attributes file://attributes.json --region eu-north-1
 ```
